도서지역은 내륙지역과 비교하여 기후 변화의 차이가 있다. 도서지역은 풍속과 바다 수온이 기온에 영향을 미친다. 같은 시기에 도서지역과 내륙지역에서 여왕벌 을 유입하여 교미충실도의 차이가 있는지 알아보기로 하였다. 실험한 결과 도서지 역의 유입율은 1차(4월 3일) 90%, 2차(4월 11일) 90%, 3차(4월 18일) 100%이고, 내륙지역은 1차(4월 3일), 2차(4월 11일), 3차(4월 18일) 100%로 동일하다. 도서지 역의 산란율은 1차 30%, 2차 50%, 3차 70%이며, 내륙지역은 1차 90%, 2차, 3차 100%이다. 섬지역의 산란소요일수는 1차 30일, 2차 20일, 3차 14일이며, 내륙지역 은 1차 12일, 2차 10일, 3차 8일의 결과를 얻었다. 산란소요일수가 많이 차이나는 이유는 최고기온 차이에 영향을 받은 것으로 보인다. 실험기간(4월 11일 ~ 5월 15 일) 중 위도격리교미장에서는 여왕벌 교미시 적정온도인 18℃이상의 일수는 도서 지역에서 17일, 내륙지역에서 39일 기록하였다. 내륙(풍양)양봉장에서는 4월부터 최고기온이 18℃인 날이 많이 관측되었다. 산란소요일수는 내륙지역의 최고온도 가 섬지역보다 평균편차와 분산이 낮게 나왔다. 이와 같은 실험결과를 통해 서양종 여왕벌 교미는 내륙지역이 도서지역보다 이른 봄철에는 최고기온이 영향을 미쳐 4 월 중순에 여왕벌 교미충실도에 있어서 높은 상관관계가 있다는 것을 알 수 있다.

Due to a high level of system ductility, steel moment resisting frames have been widely used for lateral force resisting structural systems in high seismic zones. Earthquake field investigations after Northridge earthquake in 1994 and Kobe earthquake in 1995 have reported that many steel moment resisting frames designed before 1990's had suffered significant damages and structural collapse. In this research, seismic performance assessment of steel moment resisting frames designed in accordance with the previous seismic provisions before 1990's was performed. Buckling-restrained braces and shear walls are considered for seismic retrofit of the reference buildings. Increasing stiffness and strength of the buildings using buckling-restrained braces and shear walls are considered as options to rehabilitate the damaged buildings. Probabilistic seismic performance assessment using fragility analysis results is used for the criteria for determining an appropriate seismic retrofit strategy. The fragility contour method can be used to provide an intial guideline to structural engineers when various structural retrofit options for the damaged buildings are available.

Background: To enhance the taste and physiological characteristics of Lycii fructus (Gugija) extracts, we investigated the changes in the physiological characteristics of Gugija extracts caused by adding white ginseng (WG) and red ginseng (RG) Methods and Results: Gugija extracts, including 10G10, 10GW-G8 : 2, -G6 : 4, -G4 : 6, -G2 : 8, and -G0 (mixtures made by replacing 0, 20, 40, 60, 80, and 100% of Gugija with WG), as well as 10G10, 10GR-G8 : 2, -G6 : 4, -G4 : 6, -G2 : 8, and -G0 (mixture made by replacing 0, 20, 40, 60, 80, and 100% of Gugija with RG) were extracted with water at 10 times the respective mixture's volume. The antioxidant activities of Gugija extracts were investigated by assessing their 1,1-diphenyl-2-picrydrazyl (DPPH) and 2,2’-azinobis(3ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, ferric reducing antioxidant potential (FRAP) activity, nitrite scavenging activity, and angiotensin converting enzyme (ACE) inhibitory activity. As the amount of WG added increased, the DPPH, and, ABTS radical scavenging activity, and FRAP activity of the Gugija extract decreased. The half maximal inhibitory concentration (IC50) value of 10G10, 10GW-G6 : 4, 10GR-G6 : 4, and 10GR-G0 for DPPH radical scavenging activity were 25.50 ± 1.04, 52.06 ± 1.46, 16.87 ± 1.24, and 9.50 ± 0.16 ㎕/㎖, respectively. On the other hand, the physiological activity of Gugija extract increased with the addition of increasing amounts of RG. However, ACE inhibitory activity was the highest (50.25 ± 2.58%) in the Gugija 10-fold extract without any added RG. Conclusions: From the above results, we suggest that adding RG to Gugija extracts increase their antioxidant, FRAP, and nitrite scavenging activities.

Background : Among registered fungicides for controlling ginseng disease, the disease occurrence rate from the mixed use of a single ingredient, mancozeb WP, and copper sulfate basic WP was examined, and experiments were conducted to establish safe disease control system. Methods and Results : As for the medicines used for the experiments, besides registered Pyraclostrobin WG as a single ingredient for ginseng disease control, 14 kinds were used for experiments. The fungicide was sprayed 5 times on June 21, July 4, July 16, August 2 and August 24. The examination was conducted 5 days, 10 days, 15 days, and 20 days after the final fungicide treatment. Anthracnose occurrence rate 5 days after the final fungicide treatment was 0.0 - 61.3% which was different depending on fungicides, and in a single treatment, the occurrence rate was less than 1% in 6 fungicides. In the single treatment, the occurrence rate was more than 1%, but 9 kinds of fungicides which had less than 1% occurrence rate in the case of mixed use with mancozeb, and one kind in the case of mixed use with copper sulfate basic 10 days later, the occurrence rate was 0.0 - 100% and there were lots of differences in the disease occurrence rate depending on fungicides. 10 kinds of fungicides showed the disease occurrence rate of more than 10.0% in the case of a single treatment. Among them, 9 fungicides showed the disease occurrence rate of less than 1.0% in the case of mixed use with mancozeb, indicating the effect of lowering disease occurrence rate in the case of mixed use. 15 days later, 9 fungicides showed disease occurrence rate of more than 2%, 1 kind of fungicide had the disease occurrence rate of less than 1%, and the overall disease occurrence rate increased. Among them, 7 kinds of fungicides showed the disease occurrence rate of less than 1% from the mixed use. 20 days later, 12 kinds of fungicides showed the disease occurrence rate of more than 50%, and only 1 kind of fungicide showed the disease occurrence rate of less than 1%. In the case of mixed use with mancozeb, 2 kinds had the disease occurrence rate of less than 10% and 1 kind of fungicide had the disease occurrence rate of less than 1%. Conclusion : For prevention of anthracnose disease of ginsengs during a rainy season, the disease occurrence rate from a single or mixed use was examined, and the examination found that rather than a single use, mixed use decreased the disease occurrence rate. In particular, the mixed use with mancozeb showed low disease occurrence rate and prevented the disease occurrence rate for a long time.

Background : Ginseng sometimes develops physiological disorders as EC of soil accumulates in sun shading facilities with no leaking water. In addition, it is difficult to make moisture content of soil and EC stably suitable for ginseng growth and development in the same sun shading facility. Accordingly, this study examined EC in soil depending on leaking water rate of sun shading facilities and conducted experiments to establish the proper leaking water rate for ginseng depending on rainfall. Methods and Results : For leakage examination, rainfall flowing into a ridge. As sun shading facilities of ginseng to examine leakage, four kinds such as Blue-Pe-sheet, Pe4 (four–layered polyethylene net) + Pe2 (two–layered polyethylene net), Pe4 , Pe2 were installed.

Background : The major active components of ginseng are ginsenosides and their pharmacological effects include anticanser, anti-stress, anti-fatigue, antioxidant and aging inhibitory effects. These ginsenosides components is higher in leaves than roots. Therefore, consumers are increasingly interested in using ginseng sprouts. Methods and Results : Ginseng sprouts were cultivated during 60 days from June to late July in greenhouse. After 60 days of cultivation, the stem was hardened, and the cultivation was done until 60th because of the tendency that the value of ginseng sprouts was lowered. The content of the three indicator components were analysed by high performance liquid chromatography. Total ginsenoside content increased 1.07 times in leaves and decreased 0.67 times in roots according to cultivated period. The contents of ginsenoside Rg1, Re, Rb1, Rc F3 and F4 of leaves were increased and ginsenoside Rg1, Re, Rb1, Rb2 and Rf of roots were decreased on cultivated 60 days, especially. Total free sugar content increased 1.29 times in leaves and decreased 0.68 times in roots according to cultivated period. The total phenolic acid contents of leaves decreased slightly until 40 days and then increased. The major components of ginsenoside, free sugar and phenolic acid in leaves were Re, sucrose and sinapic acid, respectively. Conclusion : From the above results, ginseng sprouts cultivated for 60 days is more effective ingredient than roots, so it can be said that it is good for consumers to use.

Background : Rural communities were facing labor difficulties due to old age and increasing number of women in the labor force. These factors have caused decrease in effectivity and productivity of ginseng production. Also, due to repetitive ginseng cultivation, salt accumulation in soil becomes more evident. When too much salt is present, ginseng plants appeared to have red colored roots and this caused the fall down of marketability of ginseng. In this study, we tested the use of wide shade facilities to enhance the growth traits of ginseng. Wide shade facilities can also reduce the working expenses of transfer cultivation and replacement by around 1,500,000 won/10a. In addition, this might also reduce the consequences of continuous cropping, thus obtaining a stable and safe field. Methods and Results : We set up 3 kind of facility as wide shade, supply type wide shade and conventional shade in Ginseng & Medicinal Plant Research Institute, Chungnam Agricultural Research & Extension Services. Wide shade facility used three different types of shade material, black, red, and blue films. Supply type wide shade facility and conventional shade used polyetylene (PE4 + PE2) film. The planting size were 10 ㎝ × 18 ㎝ (9 × 10 plants), planting number: 90 plants/3.2㎡ in wide shade (include supply type wide shade) and 10 ㎝ × 18 ㎝ (8 × 10 plants), planting number: 80 plants/3.2㎡ in conventional shade. Our results showed that temperature was lower (-0.5℃) in wide shade facility than in supply type and conventional shade. conventional shade was lower (-0.5℃) or similar than in supply type shade. We investigated growth of Korean ginseng 3-years-old root for each facility. Results showed that total growth such as root weight, length was higher in supply type facility than in wide shade and conventional shade facility. Root rot was lower in supply type facility. Conclusion : Wide shade facilities was shown in low temperature than in supply type and conventional shade. Supply type was good for root growth and root rot disease. These finding could be used for place fixed cultivation for ginseng using wide shade facility.
